Remarks

⚠ One per document, not one per pointer. A second finger arriving in the middle of a drag is a gesture the recogniser is already reading as a pinch, and two simultaneous drags with two payloads is a shape no application in this tree wants and every part of which would have to be threaded through the target's events. BeginDrag replaces an unfinished one rather than stacking it.
